WebApr 8, 2024 · In this paper, we show how a network trained according to such a strategy allows for generating, from still images, training data that well model motions, to train … WebThe optical flow is estimated as the motion between two consecutive video frames. The video frame T at the given instant tcurrent is referred as current frame and the video frame T-1 is referred as previous frame. The initial value of the previous frame at time tcurrent = 0 is set as a uniform image of grayscale value 0. Note

WebJun 20, 2024 · The basic idea behind the unsupervised optical flow models is to warp the second image toward the first image according to the estimated optical flow. The objective is to minimize the difference between the first image and the warped “reconstructed” image, except for the occluded regions [18, 19]. Such an idea works well for non-occluded ...
